GEORGE STACKHOUSE, OF BERKELEY, GALIFORN'IA, ASSIGNOR TO PAGIFIC SPRING BED COMPANY, OF BERKELEY, CALIFORNIA, A GORPORATION.

SPRING-TIE.

Specification of Letters Patent.

Patented Got. 16, 1917.

Application filed March 27, 1916. Serial No. 87,020.

To all whom it may concern:

Be it known that I, GEORGE STACKHOUSE, a citizen of the United States, residing at Berkeley, in the county of Alameda and State of California, have invented certain new and useful Improvements in Spring- Ties, of which the following is a specification.

This invention relates to improvements in means for assembling and tying together a plurality of coiled springs such as are used in bed springs.

The principal object of my invention is to provide a simple and eiiicient means, which is readily assembled for securing the upper ends of springs of this character, the bottom end resting and being securely held on any desired form of supporting struc ture.

Another object of my invention is to provide a tie which securely holds the springs in their proper spaced relation without sacrificing the resiliency of the structure as a whole.

With these and other objects in view my invention consists in the novel construction, combination and arrangement of parts herein illustrated and more specifically pointed out in the appended claims.

Reference being had to the accompanying drawing forming a part of this specification,

Figure 1 is a view in plan showing several springs in their assembled position and method of securing the upper parts in spaced relation.

Fig. 2 is a view in section on line 2-2, Fig. 1.

Fig. 3 is a fragmentary view of the connecting tie wire used to secure the upper end of the springs.

Referring to corresponding parts in the several views by thev same numerals of reference, 1 denotes the framework in which the springs are secured, and 2 denotes the s )ring coils in general. The upper portions of the coils are arranged in spaced relation preferably at an equal distance apart in each direction. They are held in this manner by means of the wires 3 crossing each other at right angles and provided at intervals with the oppositely disposed substantially semicircular curves a. The upper ends of the spring coils are provided with arms 5, which extend inwardly to the axis of the coils and there provided with the loops 6.

In assembling the ends of the ties 3 are secured in holes 7 in the frame member 1. These holes are spaced the same distance apart as the distance between the coils whereby the bend l of one tie will lie above the corresponding bend of the tie at right angles. The spring is placed under these ties and the arm 5 is passed under the upper convolution of the spring coil, the hookshaped ends 6 inserted over the alining portions of curves 4t, thus when all springs are secured in this manner the various portion of the tie forming rectangular mesh supporting structure for the upper port-ion of the spring. The straight connecting portion 3 serves to hold the springs in spaced relation, the loop 6 holding the tie wires from slipping and the arm 5 being under the top convolution of the coil prevents the loop from raising off of the curves 4:.

The tie wires rest directly on the top of the coils so that any downward pressure of these tie members carries with it the arms 5, thereby preventing any relative movement between the curves t and the loops 6.

While I have shown the preferred embodiment of my invention it will be understood that minor changes may be made in detail of construction in arrangement of parts without departing from the scope of the claims.

I claim as new and wish to cover by Letters Patent:

1. A tie for coil springs comprising tiewir'es disposed at right angles to each other, oppositely disposed adjoining semicircular curves formed in said tiewires, the curves of crossing ties being arranged to lie above each other, inwardly bent arms formed on said spring coils. U-shaped bends formed on the inner ends of said arms, the said iends being adapted to embrace the overlying curves in said tie-wires.

2. A tie for spring coils comprising, in combination with spiral springs, tie-wires disposed at right angles to each other, oppositely disposed semicircular bends formed in said tie-Wires at equal intervals, the bends of ties at right angles overlying each other, arms formed on the ends of the upper convolution of said springs, said arms extending under the convolution below to the axis of said spiral, U-shaped bends formed on the ends of said arms, said bends embracing the overlying curves, and a frame adapted g GEORGE STACKHOUSE.

Copies of this patent may be obtained for five'cents eaelnby addressing the Gemmissioner of Patents.
